BACKGROUND OF THE DISCLOSURE Technical Field

The technical field of this disclosure relates to an electric desk stand, and more particularly to a lightweight electric desk stand.

Description of Art

To fit the physique, height and habit of different users, fixed tables have been gradually replaced by electric lifting tables with an adjustable height, which have become one of the mainstreams of today's design. After the height of the electric lifting table is adjusted, the users of different heights and physiques can use the table in a comfortable manner.

An electric desk stand, such as disclosed in Taiwan Pat. Nos. TWM486995, TWM504506 and TWM560241, includes a beam structure, a pair of telescopic columns and a pair of flanks, and the beam structure is mainly formed by two rectangular tubes connected in parallel to one another and spaced apart with an interval from one another, and an accommodating groove is formed between the two rectangular tubes.

However, the manufacture of the beam structure formed by connecting the rectangular tubes requires a cumbersome and complicated manufacturing procedure and the weight of the assembled electric desk stand is relatively heavy, which is not conducive to moving and transportation. In addition, the accommodating groove is an open space, so that the electric wire connected to each electrical component is exposed, which affects the overall aesthetic appearance. Further, the heavy weight of the electric desk stand prevents the material cost from being reduced effectively, which in turn affects economic benefits.

In view of the aforementioned drawbacks of the electric desk stand, the discloser of this disclosure based on years of experience in the related industry to conduct extensive research and experiment, and finally provided a feasible solution as disclosed in this disclosure to overcome the above drawbacks.

SUMMARY OF THE DISCLOSURE

Therefore, it is a primary objective of this disclosure to provide a lightweight electric desk stand that uses a configuration of frames to achieve the effects of maintaining high stability, reducing total weight, and lowering material cost.

To achieve the aforementioned and other objectives, this disclosure discloses a lightweight electric desk stand including a beam structure, a pair of telescopic columns and a pair of flanks. The beam structure includes a lower frame and two upper frames. The lower frame includes a bottom plate and two risers upwardly bent and extended from the bottom plate and configured to be facing one another. Each of the upper frames includes a top plate and two side plates downwardly bent and extended from the top plate and configured to be facing one another. Each upper frame is mounted on the lower frame. Each side plate is lapped to each riser. The bottom plate and each of the top plates are spaced from one another and configured to be facing one another. Each telescopic column is connected to two sides of the beam structure separately, and each telescopic column includes a motor. Each flank is installed on an edge of each of the telescopic columns and covers two ends of the beam structure.

This disclosure has the following effects. The design of the insert plate and the pull buckle is conducive to a quick removal or installation of the controller. The electric wire and the connector are concealed and stored between the lower frame and the upper frame to enhance the overall aesthetic appearance. The design of the hand access hole allows users to grab, plug or remove the connector with respect to the port by hands conveniently. With the design of the mounting opening formed on the bottom plate, the controller may be detached from the mounting opening without using any hand tools, thereby improving the convenience of installation or maintenance.
